OCV Control Valves has many valve designs to meet the variety of requirements of water utility systems. By controlling pressure, rate of flow, surge and pump control, OCV’s valves can help improve the efficiency of both supply and distribution. OCV also has altitude control valves to service elevated water tanks and a digital control valves to interface with high level SCADA systems.
They are
- Diaphragm Check
- Pressure Relief
- Differential Control
- Solenoid Control
- Surge Anticipation
- Rate of Flow
- Pump Control
- Pressure Reducing
- Float Control
- Altitude Control
- Digital Electronic Control
